A lectern is a librarian's job site block found in villages. It is used to hold books for multiple players to read in multiplayer.

Obtaining[edit]

Natural generation[edit]

Lecterns can generate naturally in village libraries.

Breaking[edit]

Lecterns can be broken with any tool, but an axe mines it the fastest. Lecterns drop themselves and the book they are holding.

Usage[edit]

Lecterns are the job block of Librarians.

Lecterns can also hold a single book and quill or written book that other players can read at the same time. Right-clicking an empty one with a book and quill or written book places it. Right-clicking a lectern with a book already occupied opens an interface to read the book. Books occupying a lectern can be retrieved through the interface,‌[Java Edition only] punching the lectern‌[Bedrock Edition only] or by destroying the lectern, even when /gamerule doTileDrops is false.

Redstone signal[edit]

Lecterns holding a book emit a full-strength redstone pulse that is one game tick long (0.5 redstone ticks) when a page is turned. A redstone comparator also records book reading and sends a signal, depending on what page the player is currently on. Because Bedrock Edition displays two pages of the book at once, the same signal strength increments require double the number of pages.


For Java Edition a book with only 1 page gives maximum signal strength, however page 1 always gives 1 signal strength no matter what if a book contains at least 2 pages.

Due to this, to calculate the signal strength of books with more than 1 page, use the following formula:

Where is the "floor" operation (round down), is the maximum number of pages the book on the lectern has, and is the current page number the lectern is turned to.

This is most noticable when a book has 2 pages where the signal strength is either 1 on page 1 or 15 on page 2.

A book that would step up or down in increments of 1 per page would be 15 pages long.

For Bedrock Edition the formula is slightly different. Due to Bedrock showing 2 pages at once and counting a change to the book's output only if the highest even numbered page contains information, a redstone comparator treats books with 3 pages the same as those with 1 or 2 pages of information, the same as how Java would treat a book with just 1 page.

For 4 or more pages of information use the following formula to calculate signal strength.

In this case is half of the maximum page number rounded down, and is half of the current highest page number containing data displayed on the book interface, rounded down.

Rounding down is required to eliminate the discrepancy caused by books containing an odd number of pages. For example, a book with 8 pages gives a signal strength of 15 when looking at pages 7-8. A book with 9 pages has a signal strength of 15 when looking at either pages 7-8 and 9-10.

In Bedrock Edition, a book that steps up or down in increments of 1 per page turned must be exactly 30 pages long, with information left on page 30.

Changing profession[edit]

If a village has a lectern that has not been claimed by a villager, any villager has a chance to change their profession into librarian if those villagers have not already chosen a job site block.

Fuel[edit]

Lecterns can be used as fuel in furnaces to smelt 1.5 items.

Note Blocks[edit]

Lecterns can be placed under note blocks to produce "bass" sound.

Block data[edit]

A lectern has a block entity associated with it that holds additional data about the block.

  • Block entity data
    • Tags common to all block entities
    •  Book: The book item, without the slot tag, currently on the lectern, may not exist.
      • Tags common to all items
    •  Page: The page the book is currently on, starting from 0, does not exist if there's no book.

History[edit]

Java Edition
August 18, 2012Lectern (pre-release).png Lectern Book (pre-release).png The lectern was an old project of Dinnerbone's. It was meant to be a stand for written books, so they could be easily read. He was well on his way to creating it when he encountered problems and scrapped the idea, but mentioned that he might pick up work on the lectern in the near future.
December 18, 2013Dinnerbone states in his Reddit AMA that he has revisited lecterns, but scrapped them again as "something about them just didn't feel right".
October 18, 2018Lectern (pre-release 2).png Dinnerbone reveals that the lectern is once again in development.
1.1418w44aLectern JE1.png Added lecterns.
Lecterns are currently obtainable only from the creative inventory and have no functionality.
Lecterns currently have a BookItem field, which holds the book item to be displayed. However, this field cannot be set and is not written to the block entity.
There is a file lectern.png which has each texture of the lectern on a large sheet. However, this is unused, as separate files ae also present.
18w45aThe inventory icon of lecterns has been slightly changed from to .
Removed the unused lectern.png file.
Lectern JE2 BE1.png The texture of lecterns has now been changed.
The bottom texture of lecterns has been changed from Lectern (bottom) JE1.png to Lectern (bottom) JE2.png.
18w47aLectern (bottom) JE3 BE1.png The bottom texture of lecterns has been changed, once again.
18w48aLecterns can now generate in plains village libraries.

Lectern Book JE1 BE1.png Lecterns can now be used to hold books.
Lecterns now emit a redstone pulse when a page is changed.
Lecterns now use the correct cullface argument for its bottom face.
?Lecterns now use some corrected side cullface arguments for the front and back of their base plate.
19w03aCertain blocks can no longer be supported by the top of a lectern.[1]
